China Pharmaceutical Aluminum Foil Suppliers - High-Quality Factory Packaging for Tablets and Capsules
Common Types
-
Single-layer pharmaceutical aluminum foil: Rolled from pure aluminum, mainly used for simple sealing or as a composite base material.
-
Composite pharmaceutical aluminum foil: Combined with plastic films (e.g., PVC, PE) or paper, integrating the barrier property of aluminum foil and the flexibility of other materials. It is widely used in blister packaging (PTP aluminum foil).
-
Coated pharmaceutical aluminum foil: Coated with pharmaceutical-grade adhesives and protective layers on the surface to improve sealing performance and printing adaptability.
Main Application Scenarios
-
Blister packaging (most common): Cooperates with plastic blisters to individually package each tablet or capsule, facilitating portability and administration.
-
Pouch packaging: Serves as the inner barrier material of composite pouches for large packaging of granular preparations and powders.
-
Bottle cap sealing: Used as aluminum foil gaskets for medicine bottle mouths to enhance sealing effect and prevent drugs from dampening and deteriorating.

Frequently Asked Questions
Why is aluminum foil preferred for pharmaceutical packaging?
Aluminum foil provides an absolute barrier against moisture, light, oxygen, and other gases. This protects sensitive medicines from environmental degradation, ensuring their safety, efficacy, and longer shelf life.
What is PTP aluminum foil?
PTP (Press-Through Packaging) foil is a specialized composite aluminum foil designed for blister packs. It allows users to easily push tablets or capsules through the foil while maintaining individual airtight protection for the remaining doses.
Is pharmaceutical aluminum foil safe for direct contact with drugs?
Yes, pharmaceutical-grade aluminum foil is coated with non-toxic, food-safe protective primers and heat-seal lacquers. These coatings prevent any direct chemical reaction between the aluminum metal and the pharmaceutical compounds.
What is the difference between single-layer and composite foils?
Single-layer foil consists of pure rolled aluminum, ideal for basic sealing or as a raw base. Composite foil is laminated with plastic films (like PVC/PE) or paper to combine the barrier properties of aluminum with the flexibility, durability, and sealing strength of other materials.
How does bottle cap foil sealing protect medicines?
Bottle cap gaskets (often applied via induction sealing) create a hermetic seal over the bottle opening. This seal acts as a tamper-evident barrier and prevents moisture, humidity, and airborne contaminants from entering the bottle.
